UNITED STATES PATENT OFFICE JULIUS M. JAGEL, OF BROOKLYN, NEXV YORK ELECTRIC SUBWAY.

GPECIFICATION forming part of Letters Patent No. 349397, dated September 28, 1886,

Application lllel March 1. 1886.

TO all whom, it ?way concern:

Be it known that I, JULIUS M. JAGEL, ot' Brooklyn, in the county ot' Kings and State of New York, have invented an Improvement in Electric Subways, of which the following is a specification. I 4

Hollow railway-rails have been made for the reception of electrie eonductors; but the rail,

had to be removed to give access to the conduit containing the eonductors;

My invention is forfurnishiug a continuous eondnit that can be opened all along the top, for the reception ot' cables, pneumatic tubes, or wi res, without disturbing the railway-track; tor supporting railway-railsin a firm and rigid manner without interfering with the access to the conduit 'for inserting or removing the eonductors, and for allowing the rails to be attached or removed at pleasure; for drawing into the conduit insulated eleetric eonductors as required from time to time, and for allowing ot' the lateral connections to be made 'for branch wires.

In the drawings, Figure 1 is a cross-seetion of the conduit, representing the same as complete. Fig. 2 is a section in larger size of the device l'or drawing in additional wires or cables. Fig. 3 is a section longitudiually at one of the access-openings, and Fig. 4 is a section of one ot' the short reinovable covers.

The conduit A is made of the bottom 1, sides 2 and 3, compound curved roof 4 5, Vertical checks (i 7, bearing-fianges S 9 for the cover, and tread-plate 10 for the traek-rail. These conduits are prel'erably ot' iron, cast in suitable lengths, and the ends are brought together, there being end flanges, ll, at one end of each conduit, receiving within them the end of the next length. Rubber strips should be placed between the ends, as at 12, and the bolts 13 pass through the metal, and are made tight by washers beneath the heads, and the holes in the flanges are elongated to allow for expansion and contraetion. The tread-platc 10 is about the same width as the langes of the rail B, and there are openings in the tread-plate for the passage of the bolts 15, by which such rails B are secured. There may be keys inserted to hold these bolts down to place, or there may be nuts on the lower ends. In either case there are lateral openings beneath the tread-pla te to give access to the nuts or keys 5 Serial Ne. 103,(31'7. (Ne modul.)

or the tread-plate may be supported by llanges extending above the root' 5 to the under side of the tread-plate, and placed sufficientlynear each other to firnl y support such tread-plate. These treadplates are at one side of the longitudinal opening and above one side of the box, so that the weight of the cars is supported directly by the side of the box. Thecover G rests upon the fianges S and 9, there being a packing of rubber or similar material between the metallic surfaces to render the joint water-tight, and the rib and groove at 16 serve to render the connection more reliable. The cover G may have bolts passing into the cheek G tohold the same firmly, and this cover is preferably corrugated or ronghened on its upper surface, and the ends of the covers lap upon each other, and are packed or otherwise rendered water-tight. The covers C are in lengths that are easily handlcd; but at suitable distances apart say about every three hundred feet-accessopenings are provided with short removable covers C', made similar to the covers O, so that by removing such cover C' access can be had to the wires. It is to be understood that When the covers C are removed large cables containing numerous wires can be laid into the conduit, as at E, or pneunatic tubes can be introdueed, as at F. These should be laid in the bottom of the conduit, and the smaller cables or eonductors, E, should rest upon them. The bottom of the conduit is provided with ribs or supports 18, placed at short intervals, to keep the tubes and eonductors up from the bottom, and these supports are to be notched, to allow any water that may get in to run along to a low place and be taken off to a sewer.

In order to allow for the insertion of conduetors from time to time, I provide the endless wire ropes 21, passing around the pulleys 22, that are upon gudgeons 23, fixed in the conduits at the access-openings, and there is an upper tube, 26, of iron, through which the wire rope passes, and a lower split case, 27, also for the wire rope to pass through, and these pulleys 22 are to be revolvcd by a band, 28, to a pnlley, 29, in a frame aboveground, as shown in Fig. 3, such. pulley 29 being turned by a erank. Upon the wire rope a suitable appliauce, 42, is attachcd for con necting to the conductor or cable This ap- IOO pliance hangs down through the slot in the split case 27. The case 27 and tube 26 are supported at intervals by hangers 30. Handhole openings are castin the conduits at suitable distances apart, and by having these in the arched roof 4 they are easy of access, and the covers 43 of these hand-holes can be attached by tnbular bolts, as shown, so that the insniated conductors can be taken oti' through small iron pipes serewed onto the tubular bolt. v

It is to be understood that both rails of the track are to be laid on conduits, so as to render the track uniform and increase the capacity for the reeeption of conductors, and one conduit may receive pneumatic tubes and electric-light wires, and the other teleg'aphwires and telephone wires and cables.

I claim as ny inventioni 1. The Conduit for electric conductors, formed of ranges of metal boxes bolted together, each box being formed of the bottom 1, sides 2 and -3, the curved roof portion, with the vertical checks forming the sides of the longitudinal openings, and the tread-plates 10, for the reception of railway-rails at the top and on one side of the longitud-inal opening, in combination with the removable covers, substantially as set forth.

2. The combination, with the condnit for electric conductors, of thepuileys, the endless and tread-piates at the sides of the openings 0 for the reception of the railway-rails, in combination with the removable covers in the 1on gitudinal openings,whereby access is given to, the conduit Without disturbing the rails, and

t-he rails are removabie fron the tread-plates 45 independent of the covers, substantially as specified.

4. A combined sieeper for a railway-track anda conduit for eleetric conduetors, formed of a range of cases, each having the sides arching toward each other, a tread-plate for the railway-rails, and a iongitudinal opening with paral lel sides and covers having parallel edges that fit tightly into the longitudinal opening, substantially as set forth.

Signed-by me this 20th day of February, A.
